ROLLER-GATE HINGE.

SPECIFICATION forming part of Letters Patent No. 350,334, dated October5, 1886.

' A pplication filed May 28, 1886. SerialNo. 203,534. (No model.) I

To all whom it may concern:

Be it known that I, PETER M. WOLF, a citizen of the United States,residing at Plymouth,

in the county of Sheboygan and State of Wisconsin, have invented certainnew and useful Improvements in Rollers for Swinging Gates; and I dohereby declare, the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of ref erence markedthereon, which form a part of this specification.

The present invention relates to gatehinges of the class provided withrollerson which the gate can roll; and the object of my invention is toprovide an improved gate-hinge which will not allow the gate to jump thetrack, so to speak, and which also will work easilywithout friction.

The invention consists in the improved construction and combination ofparts hereinafter fully described and claimed, the same comprising alarge slightly-flanged roller journaled in the top of an H-shapedcasting and a small roller with wide flanges journaled in the bottom ofthe same casting, which casting also has two lugs on one side forattachment to a hinge-plate by a pivot-bolt.

In the accompanying drawings, Figure 1 represents a side elevation of agate and roller hinge constructed according to my invention. Fig. 2 is adetail sectional view, and Fig. 3 is a side view, of the roller-hinge.

The frame A of the rollerhinge is made of a single casting in the formof an H, with two lugs, a, projecting from one side opposite thecross-bar a of the'frame.

B is the top roller, journaled between'the upper arms of the H-shapedframe, and made concave on both sides to give free play between itsbearings. The flanges on the roller Bare very narrow, so as to cause aslittle friction as possible, for it has to carry the whole weight of thegate, and they are made just deep enough to retain'the bar M of the gateon the roller, acting in concert with the lower roller, 0.

-The guide-roller G is journaled between the bottom arms of the H-shapedframe, and it has wide flanges which embrace the bar N of the gate andprevent the gate from jumping off the roller B. When the gate is movedlaterallyon the roller-hinge, the friction of the gate-bar N on theflanges of the roller 0 tends to rotate it in the opposite directionfrom that in which the roller B is turning, and the roller 0, being anindependent roller, is' free to rotate. The gate-bar N can also set upclose to the roller 0, so as not to allow any vertical play to the gateon the rollers, all of which tends to make the gate work easy andprevents it from getting out of place. The rollers are made in two partsfor convenience in casting. The hinge-plate D has holes d at the top andbottom for attaching it to the gatepost, and has a lug, d, which, inconnection with the lugs a and a bolt, E, forms a hinge on which thegate can be swung.

I am aware that hinge-rollers for gates have been used prior to myinvention, and that the rollers have been made both plain and flanged,

and have been journaledin H shaped castings.

I do not, therefore, claim any of these things, broadly.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The H shaped casting hinged on one side to a plate for attachment toa gate-post, and having the large roller B with narrow flanges journaled between its upper arms, and the small roller 0 with wideflangesjournaled between its lower arms, substantially as shown anddescribed, and for the purpose set forth.

2. A gate-hinge consisting of the hinge-plate secured to the gate-postand provided with the projecting lug d, the H-shaped casting providedwith lugs a, the hinge'pin connecting .the said lugs, the large rollerhaving narrow flanges journaled between the upper arms of the saidcasting, and the small roller having Wide flanges journaled in the lowerarms of the said casting, substantially as set forth.

In testimony whereof I afflx my signature in presence of two witnesses.-

PETER M. WOLF.
